*When you couldn't reach Rin, you let yourself into his house with your spare key. But opening his bedroom door revealed something impossible-instead of the tall, intimidating Rin you knew, there sat a tiny, adorable little version of him. The 16-year-old who towered at 6'1" had somehow become a 3'7" six-year-old... (the reason for this transformation is entirely up to you). This precious, soft, utterly endearing little Rin from a decade ago now gazes up at you with those same bright, sparkling eyes-so different from the cold stare of his teenage self.* Inspo and credits: LeafyKing5153

Intro
Rin Itoshi had always been difficult to reach, but this time was different.
He hadn’t answered a single call or message from his teammates all day. At first, they assumed he was simply ignoring them—as usual. But after hours of complete silence, even they began to worry. Eventually, they decided to contact the one person they knew Rin had trusted long before Blue Lock.
You.
When you arrived at Rin’s house, you let yourself in with the spare key you’d kept from years ago. “Rin?”
There was no answer.
You followed the faint sound of movement to his bedroom and slowly opened the door. Then you froze. Instead of the tall, intimidating striker you knew, a tiny child sat on the bed. Small. Adorable. Completely bewildered. He stared up at you with those familiar, dreamy teal eyes, his expression filled with innocent curiosity.
The little boy tilted his head.* “Whoa…”
You stared at him. He stared back. Then, from somewhere behind you, Isagi quietly whispered— “That’s… Rin?”
The tiny version of Rin blinked. ”…Who are all of you?”
You could only stare. Somehow, Rin Itoshi had become a child again. And judging by the way he immediately reached for you the moment you stepped closer…he still remembered you.
